What is the recursive rule for an=3n+5

Aa1=5;an=an−1+3

Ba1=8;an=an−1+5

Ca1=3;an=an−1+5

Da1=8;an=an−1+3

Verified Answer :

Answer:

Option d is correct.

Step-by-step explanation:

We have given a formula \(a_n=3n+5\)

We will put different values of n so, as to get \(a_n\)

from the given formula

When n =1  we get

\(a_1=3(1)+5=8\)

When n=2 we get

\(a_2=3(2)+5=11\)

When n=3 we get

\(a_3=3(3)+5=14\)

We can see that next term is 3 more than the previous term

Hence, \(a_1=8;a_n=a_{n-1}+3\)

Therefore, Option d is correct.
